Do stuff to distract yourself as much as possible despite the fact that your mind may keep staying fixated on it. It's the worst feeling in the world (I didn't eat or sleep for 3 days) if you really cared about the other person. Try to think of it as a physical injury that will heal. I love how my friends made plans just for me and dragged me out. During that time, it felt like a hassle and all I wanted to do was sit in my room and be emo but, when I look back now, I can see that they understood that spending time doing fun stuff really does help.

They took me my favorite Thai restaurant and bought me my favorite thing there, which I didn't eat. They forced me to take cue pictures, which I complained about. They stayed with me for like 3 days even though I just wanted to be alone.
